Get it out of your head. Saydo remembers. Say what’s on your mind, exactly how it comes out. “Call the dentist, pay rent Friday, gym at 6, pick up dry cleaning.” Saydo turns it into separate tasks and events, adds timed plans to your calendar, and reminds you so nothing slips. JUST TALK Ramble, change your mind halfway through, or say five things at once. Saydo sorts it out and shows you what it understood before anything is saved. REMINDERS THAT GET THROUGH Get reminded when it matters, even during Focus. Set reminders naturally by voice: “Remind me an hour before.” YOUR CALENDAR, NOT ANOTHER APP Events sync directly with your Apple or Google Calendar. Your plans stay where you already look, using the calendars and colors you already have. CHANGE PLANS BY VOICE “Move the dentist to Friday.” Saydo understands the change, shows it to you, and updates your calendar. No menus. No manual editing. ONE SIMPLE LIST See everything you’ve said in one place, with today at the top and everything else organized by day. Built for anyone with too much on their mind and too little time to type it all out.
